Abstract
Abstract Improved rotary cutting apparatus and method of making the same incorporates a thin deposited layer of diamond particles in nickel disposed about the periphery of a rotatably body. The deposited layer is exposed beyond the periphery of the body during the fabrication process to provide high-speed cutting apparatus for use on semiconductor materials.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
67 words
Cutter apparatus comprising a rotatable body having a relatively thin surface near the periphery thereof which is substantially normal to the rotational axis of the body; and an electroformed unsupported layer of a matrix of diamond particles in a nickel binder disposed on said surface, said layer having substantially parallel sides protruding radially beyond the periphery of said body and forming a relatively thin homogeneous cutting blade.
Claim 2
Dependent Claim
67 words
Cutter apparatus comprising a rotatable body having a relatively thin surface near the periphery thereof which is substantially normal to the rotational axis of the body; and an electroformed unsupported layer of a matrix of diamond particles in a nickel binder disposed on said surface, said layer having substantially parallel sides protruding radially beyond the periphery of said body and forming a relatively thin homogeneous cutting blade.
Claim 3
Dependent Claim
14 words
Cutter apparatus as in claim 1 wherein said layer is approximately 1 mil thick.
Claim 4
Dependent Claim
37 words
Cutter apparatus as in claim 2 wherein the major radius of said layer is greater than the radius of the periphery of said body by at least 10 mils for cutting through such thickness of a material.
Claim 5
Dependent Claim
15 words
Cutter apparatus as in claim 1 wherein said electroformed layer is from nickel sulfamate bath.
